Just like we can declare an array of int, float or char etc, we can also declare an array of pointers, here is the syntax to do the same. Syntax: d…
returnType(*arrayName[])(parameterTypes) = {function_name0, ...}; (example code) As aparameter to a function: int my_function(returnType(*parameterName)(parameterTypes)); (example code) As areturn value from a function: returnType(*my_function(int, ...))(parameterTypes); ...

The following are some common uses for pointers: To access dynamic data structures such as linked lists, trees, and queues. To access elements of an array or members of a structure. To access an array of characters as a string. To pass the address of a variable to a function. ...
As a function pointer type alias: using typeName = returnType (*)(parameterTypes); (example code) As a function type alias: using typeName = returnType (parameterTypes); (example code) This site is not intended to be an exhaustive list of all possible uses of function pointers. If you...

Here we declare an array of seven integers like this: int nums[7] = {54, 6, 23, 45, 32, 78, 89}; Let's assume that the first element of the array scores has the address 1200. This means that &nums[0] would be 1000. Since an int occupies 4 bytes, the address of the second...
To dynamically create a 2D array, you first declare a double pointer. Then, you allocate memory for each row using a loop, effectively creating an array of pointers to arrays. It’s crucial to free the allocated memory properly to avoid memory leaks. This involves freeing each row first, ...
